Incinerator with fixed fire grate

Abstract

The invention belongs to the field of waste incineration devices and particularly relates to an incinerator with a fixed fire grate. The incinerator with the fixed fire grate is used for incinerating biomass materials such as straws and at least comprises a main combustion chamber, an air supply assembly and a smoke flue for guiding heat energy in the main combustion chamber out. The main combustion chamber is communicated with the smoke flue through a ventilation pipe, and a conveying and incinerating platform is arranged in the main combustion chamber and at least comprises a bearing plate and a stirring portion. The incinerator with the fixed fire grate further comprises a pushing portion, wherein an air return moisture removal cavity channel is arranged between the pushing portion and the main combustion chamber in a transition mode and forms a material conveying path for connecting the cavity of the main combustion chamber with the pushing portion, an air outlet is formed in the end of the air return moisture removal cavity channel and communicated with an external air draught fan, and the end of the air return moisture removal cavity channel and the pushing portion are positioned at the same end. The incinerator with the fixed fire grate is high in operation reliability and incineration efficiency, low in cost and capable of ensuring incineration at high and constant temperature and extracting and utilizing efficient heat energy of biomass fuel.

Description

technical field

[0001] The invention belongs to the field of garbage incineration equipment, and in particular relates to a fixed grate incinerator for burning straw and other biomass materials. Background technique

[0002] With the gradual advancement of social science and technology, the country's quality supervision of the air environment has become increasingly strict, and the past self-incineration of biomass materials such as straw has been unable to be recognized by the country. Most of the existing treatment methods for the above-mentioned materials are purchased by the incineration plant and sent to a special movable grate furnace for systematic incineration. The various gases and smoke produced by the incineration are also purified by the incineration plant itself. Conditions to be purified before being discharged into the outside air. At present, the above-mentioned incineration methods of straw, due to the consideration of its own rapid combustion and short com...
